Multi-level water level identification circuit with two detection lines for detection

Abstract

A multi-level water level identification circuit with two detection lines for detection is formed by a system power supply, a probe circuit, detection lines, and a multi-level water level identification indicating circuit. By virtue of the conductivity of water, voltage differences are formed due to voltage stabilization characteristics of voltage-regulator tubes and used for detection and identification. Identification indication is clear at a glance. Only two detection lines are needed between the indicating circuit and the probe circuit for detecting and identifying the level of the water level. When the voltage of the system power supply is increased, and the number of levels of a detecting circuit and the number of the levels of a corresponding identifying circuit are increased, the number of detection levels is increased. The line length is controlled, so that line material can be substantially saved. The wiring is simple, the maintenance is convenient, and the circuit is stable and reliable.

Description

Technical field: [0001] The invention relates to the field of electronic control, in particular to a multi-stop water level identification circuit detected by two detection lines. Background technique: [0002] ①. It is sometimes inconvenient to check and identify the water level on site. Checking the water level is time-consuming and laborious, and even unsafe. [0003] ②. The water level recognition circuit generally has more than one line for each block; the number of water level blocks to be detected is large, the detection lines are many, the wiring is too much, and maintenance is difficult; the existing water level recognition circuits are too complicated and difficult to promote. Invention content: [0004] The object of the present invention is to provide a simple and reliable multi-stop water level recognition circuit with a simple and reliable circuit in view of the insufficient current situation of the existing water level recognition circuit. The voltage diffe...
